Attitude adjustment - Can people really change?

[Arthur Dent]

In all seriousness, if you look back on who you were 5 years ago and don't see a significant difference between who you were then and who you are now, then somethings wrong. If 5 years from now your not significantly different from who you are right now, than somethings wrong. You should be contantly changing. Either because you make a real effort or just because of life and the things that happen to you.

Yes, people change all the time. It's just a slow process. If you don't, it's because your stubborn, unyielding, and ultimately stagnant.
